The vulnerability identified as CVE-2006-1006 represents a critical SQL injection flaw in the sendcard.php script of the sendcard application prior to version 3.3.0. This vulnerability falls under the broader category of insecure input handling and demonstrates a classic weakness in web application security where user-supplied data is not properly sanitized before being incorporated into database queries. The affected application appears to be a card sending system that likely facilitates the transmission of electronic cards or messages between users, making it a potential target for malicious actors seeking to exploit database access.
The technical implementation of this vulnerability stems from the application's failure to validate or escape user input parameters before executing SQL commands against the backend database. When remote attackers submit malicious input through unspecified parameters within the sendcard.php script, the application directly incorporates this unsanitized data into SQL query construction without proper input filtering or parameterization. This allows attackers to manipulate the intended database operations and potentially execute arbitrary SQL commands, which could lead to unauthorized data access, modification, or deletion. The vulnerability is classified as a CWE-89 SQL Injection, which is one of the most prevalent and dangerous web application security flaws according to the CWE database.
The operational impact of this vulnerability extends beyond simple data exposure, as successful exploitation could enable attackers to gain comprehensive access to the underlying database system. Attackers could potentially extract sensitive user information, modify or delete database records, and in some cases, escalate privileges to execute system-level commands if the database user has elevated permissions. The unspecified parameters suggest that multiple input vectors within the sendcard.php script are vulnerable, increasing the attack surface and making exploitation more likely. This vulnerability aligns with ATT&CK technique T1071.004 Application Layer Protocol: Web Protocols, as it exploits weaknesses in web application protocols to gain unauthorized access to backend systems. The impact is particularly severe because the vulnerability affects the core functionality of the card sending application, potentially compromising user privacy and data integrity across all card transmission operations.
Mitigation strategies for this vulnerability require immediate implementation of proper input validation and parameterized queries. Organizations should upgrade to sendcard version 3.3.0 or later, which includes the necessary security patches to address this SQL injection vulnerability. Additionally, implementing proper input sanitization techniques, using prepared statements or parameterized queries, and conducting regular security code reviews are essential measures to prevent similar vulnerabilities. Database access controls should be reviewed to ensure that application users have the minimum required privileges, and comprehensive logging should be implemented to detect and respond to potential exploitation attempts. The remediation process should also include network segmentation and monitoring to prevent unauthorized access to the database server and to detect anomalous database access patterns that may indicate exploitation attempts.
